Yesterday I spotted a squirrel in my yard with a large swelling under his chin. I can’t get too close, but it appears fur covered. He is still active today and eating a lot (demolishing my sunflowers), and doesn’t appear to be drooling. I doubt I could catch him at this point to provide care, but am wondering what it could be and if it might be contagious to other animals. I haven’t seen this on any other squirrels. I’m so worried about him! I hope the photos work, sorry if they’re blurry, I tried my best to set up a photo op.
